DFU mode, this indicates how to put a device into dfu mode. You are already there, but the link may be of help, otherwise doe a google search for "dfu iOS":

If this doesn't help, take it to an Apple store. There have been very few posts involving an error 3, and the one or two that do indicate that Apple has said there's a hardware issue.

Feel as though I have tried almost everything on my iphone 5 ios 7.0.4 ...starting to wonder if there will ever be a fix.


I tried DFU mode.

I tried Tinyumbrella 7.0.2.

I tried Redsn0w 0.9.15b3.

I tried Recboot.

I tried editing host file.

I tried removing host file. (put host file back after)

I even tried the "freezer fix".

Next up is IOS 7.0.1 which is taking forever to download.


Everywhere I've googled people are saying not even Apple can fix it.


Nothing. Why did I ever restore this phone. 😟

hi there i got past this error 3


first thing i did was remove the host file from C:\WINDOWS\system32\drivers\etc

then click start and choose run

in the dialog box type cmd then click ok

after the DOS prompt type ipconfig /flushdns and press enter,make sure you enter a single blank space after ipconfig.

then put what ever device you have into dfu mode and restore.

sorry i dont know how to do this on a mac. hope this works for yous having trouble

I was hoping this would make my day. Unfortunetly I followed your steps, but still got the error 3.


The problem is I am not in the states and I bought the phone from apple store.


The phone is still under warranty. Any advice on way forward.


I need apple to take it and give me a new one.


I just hate this hardware problem. Never had it on my previous 7 apple products!!


Thanks for sharing your solution.


By the way, i had another host file called host SAM. I did not remove at the beginning, and I removed then,


but NO LUCK 😟

if you have apple care and are overseas they can order you your us version but you will have to wait a couple days, they just cant swap on the spot bc they have diff 5> models. i have same problem,same dead antenna, error 3, cant use phone at all now. at least before i could use it on wireless... now im w/o phone for a few days til my replacement arrives
